System and method for controlling deviation of failure of an inverter with multiple levels in cascade.

摘要

Abstract invention patent: "control for deviation of failure mu00faltimplos levels inverter in cascade. The invention relates to an inverter with multiple levels in a cascade which is controlled in the operation of deviation of failure. Instead of relying on approximations or forms of feedback, the electric tensions of reference are generated as an analytical solution.The analytical solution and its implementation are not affected by the output frequency of the inverter and he is able to provide maximum electric voltage balanced line to line for a three phase motor.In addition, the analytical solution provides exact limits for the region of operation can be allowed the power factor of the motor so as to prevent conditions of electrical voltage in excess of the inverter cell.
